American Airlines and British Airways are now offering you lots of bonus miles if you register and fly with them now through 1/31/14.  While I usually only book reward flights on British Airways, I do sometimes pay cash for my American flights, so this could come in handy.  This is a perfect deal for the business traveler!  One business class flight and you have 25k bonus points on top of whatever you would normally earn — that's a free domestic flight right there which could be worth anywhere between $250 to $700.  If you have a choice between the two I would stick with American as the points are more valuable and easier to book.
